Setting Up Git Using git config

Git configuration helps set up your identity and preferences so Git can track changes correctly and work according to your workflow.

• Defines user identity (name and email) for commits.
• Allows customization of Git behavior and defaults.
• Ensures consistent and efficient version control usage.

Working of Git Configuration

• Git settings are stored in different configuration files at system, global, and local levels, defining how Git behaves.
• Local configurations take priority over global configurations, and global configurations override system configurations.
• Git provides the git config command to set and modify various settings related to user identity, repository behavior, and preferences.
• The git config --list command allows users to see currently applied settings from all configuration levels.
• Users can create aliases, define default branches, and set up preferences to enhance workflow efficiency and usability.

Steps To Setup Git using Git Config

Step 1: Install git

The first thing you have to do is install git in your system to proceed further. Follow these articles according to your system.

Step 4: Set global email

Set your email for all repositories by using the command

git config --global user.email 'user email'

Step 6: Configuring the Default Branch Name

By default, Git used to initialize repositories with the master branch. You can change this to main or any preferred name.

git config --global init.defaultBranch main

Step 7: Create an alias for a command

Git aliases allow you to shorten commonly used commands. Allowing git st instead of git status to work the same
